This invention relates to aline-printing typewriter or the like machines'with prepara` may be adapted according to their position to take with them through differ-ent distances devices for lifting magazines or devices for determining the position of type bars in the writing position. This maybe effected owing to the fact that the abutmentsengage stationaryl projections on these devices. Supplementary abutments capable ofbeing engaged or abutmentsresulting in the` adjusted abutments cominginto action earlier or later. These supplementaryabutments are preferably arranged on rockable levers, and the roekable levers, eorrespondingto one another, of the individual adj acent` rowsof abutments are preferably rotatably7 supported uponcontinuous shafts. AThe boxes or the likercarrying the movable abutments ,are vpreferably horieffectcd by means of astation:Y device brought within reach of the adjusted abutments during the-return movement of the box or the like carrying the abutments, into its poT sition of rest. This device preferably consists of cross-bar which participates. in the movement of the box for the purpose of acti the devices for adjusting thetype carriers nto the writing position, andupon the retina of .the box into its origi nal position, remains stationary until it hasefi'ected thereleasing of all the adjusted abutments. The r able ift levers are preferably so d-esigned'that they arerocked back into their' normal position upon the adjustment being The normalizing` or mupon` effected by means of the cross-bar or the like effecting the general release. The movable abutments'serv-` ing for moving' the rockable shift levers are preferably guided back to their'position of rest'by means ofa stationary abutment during the forward movement of the boXor the like. The apparatus which brings the type bars or the magazines containing the type into the predetermined position for writing may consist of rods which are lguided'in rakeslike members of the boX or'the like. The rods may comprise projections against which' the boX strikes during its return movement, so'that it takes the bars with it in its further vmovement and thereby returns the movingv device for the i magazines and the typebars to the positionl 'of rest, Thepbars serving for liftingthe lmagazlnes are preferably `connected by a slotguide with the levers that lift the magazines.

Y The invention is illustratedby way of eXk `ample in the accompanying drawings where- 'Y 1n VFigureV 1 shows a 'longitudinal section through a line-printing typewriter according to the invention in the. position of rest, i l I `igure` 2 a similar longitudinalsection through the machine in a position in which the type bars are brought into the writingY position,

The keysl l pivoted to 'the machine may' act.

in aknownmanner upon Vbars 2 movable in Atheir longitudinal' direction.v in lsuch a' Way that upon a key being depressedin the direc-v tion of the arrow a the bars 2 move fromrv left to right in thev direction'of th-e arrow b.- Thel movement'of these bars may beeffe'cted by the keys either directly, as illustrated in the drawing, or indirectly, in a manner notl illustrated, by means of eecentricsengageable by the keys and moved by means ofcontinuously rotating rollers. 4Each of the bars 2 con-V nected each with one key'is provided with teeth or projections 3 whichfcan .act `nfa known manner upon rockalole bars4 in'such a Vway'that the latter, during the movement of the bars inthe direction `of -thearrow b, are vrocked, by afdefiniteamount., Thejroeking ing depressed the bar 2 connected with it isV bars 4 act in a known manner upon the adjusting flaps or hammers 5 of an adjusting mechanism 6 travelling step by step transversely through the machine in the direction of the arrow c (F ig. 3). 7 7 are bars sli dable in their longitudinal direction, which at one end receive in a slot 25 a transverse pin 2G of a bell-crank lever 8 rotatably supported upon a stationary shaft. The arm of the bell-crank lever 8 which is not connected with the bar 7 acts upon the bottom member of a magazine 9 in which a series of type bars ll are arranged, lying one above the other. l0, 10 are bars or pushers, slidable in their longitudinal direction and having a U-sh aped bend at one end, which are adapted to move the type bars which lie in front ofthe ends of their upper parts, out of the magazines and between the blades l2V of a mechanism 13 whichin a known manner serves for ustifying the line formed by the adjusted type bars. let is a table-plate upon which the type bars ll rest in the justifying mechanism 13, while l5, aremechanisms which are pressed downwards on to the type bars, engagein notches on the upper side of the type bars, and thereby bring about an alignment of the type bars. The line vof printing formed by the type bars is caused, after being inked, to produce anV impression in a manner known in itself by depressing the platen 16. The adjusting hammers `5 co-operate with adjustable projections, suchfor example as bell-cranklevers 21,31 which are carried by boxes or frames 2G, 30. The abutments 2l, 3l are arranged in a plurality of adjacent rows which consist of a number of abutments located one behind the other, upon stationary transverse shafts 29 carried by the boxes 20, 30. The number of adjacent rows `of these abutments corresponds to the maximum possible number of characters of the widest line capable of being produced by means ofthe machine.

` The method of working of the machine up to this point is as follows z--Upon a key l bemoved in the direction of the arrow Za. The projections 3 on this bar each act V upon a definite rocking bar 4, whichin its turn rocks a definite ad'ustinofha-mmer 5 of the ad'usting' mechanism 6 in such a way that the adjustable projection or bell-crank lever 2l of the upper case or box 20, or 31 of the lower case 30, standing'just opposite to the Said adjusting hammer 5 is adjusted in such a way that it projects with one of its limbs beyond the `upper or lower'edge of its case. Each bar 2 bar stl, so 'that the latter is rocked each i e a key is struck. This rockingbar al brings about in a known manner the feeding `forward is in contact by one of its ends with a rocking `ofthe adjusting mechanism '6 in such a inan- V ner that the-lattery (like the paper carriages inthe case of ordinary typewriting machines) upon the key being released, is fed forward an amount corresponding to one tooth on a rack, so that it can now act with its adjusting hammers upon the adjacent row of projections 2l, 3l. In this manner for each character of the line to be written, a definite projection SiV and Q1 is adjusted.

After the adjustment for the whole line is terminated and the adj Listing mechanism has reached the end of its `path the cases and 30 `are moved in the direction of the arrows e. Under these circumstances the adj usted projections 21 and 31 engage corresponding projections andl 32 on the bars and l0 respectively and take these with them up to the end of their movement. The upper case 20 is moved first and by the movement ofthe bars 7 and bell-crank levers 8 a lifting of the individual magazines up to a predetern'iined height is effected. All the adjustedv projections of the box 2O follow the `saine path, while the bars 7, according to which bell-cranklever 2l is adjusted, are carried along a different distance. In the movement-of the lower case the push bars 10 are tak-en with them in a similar manner, by the adjusted abutments 3l, through different distances inthe direction of the arrow d and these push bars vmove the type bars lying in front of them out of the magazines, as men` tioned above. l

rlhe restoring of the adjusted projections 2l and 3l, that is to say the returning` of these projections into their` positions of rest, is effected in a simple manner by cross-bars 9S and 38 respectively, which participate in the motion of the boxes or frames 2O and 30 respectively in the direction ofthe arrow e, but inthe case of the direction of this movement being reversed, they are held fast in a convenient manner until all the rows of projections have travelled pastbelow or above them. Upon' striking' against this bar the adjusted projectionsQl or 3l are returned of themselves to their positions of rest. rifterthe releasing is comple-'ted the bars 28 and 8S are automatically brought back into their positions of rest. The returning of the parts that move the magazines, that is', of the bars and of the push bars 10 that move the type bars out of the magazines, is effected in a simple inanner'by stationary projections 27 and 37 respectively on the said parts, which are carried along by the rear walls of the boxes 2O and 30 during their return nievement. The bars 7 are supported in theiracklike or comb-like walls 23 and 24, Fig. 2, of the upper case 20, so that an accurate meeting of the adjusted projections and of the stationary projections of these bars is ensured. The ends of the bars 7 might also be pivotally connected with the bell-crank levers 8 that lift the magazines in a manner different from the manner illustrated in the drawing.

The movement of the cross bars 28 and 3S may be effected, for example, by an arrangement Asuch asV shown in the Patent No.

1,669,932. According to the disclosures of this application the cases 20 and 30 may be moved to-and-fro as above described, for instance by rods actuated by a cam vwheel on a shaft, and the cross bars 28 and 38 may be moved toandfro, for instance, by other rods actuated by aV cam wheel on the saine shaft. Thus the movement of the cross bars is dependent on the movement of the cases and can be made without difiiculty (for instance by a respective vformingof t-he cam wheels) in such a manner that when the cam" wheels lare rotated, the cross bars are moved together with the cases in the forward movement of the cases, (arrow e) and then held fast during the backward movement of ythe cases, and then moved back after the backward movement of the caseslias ended, as above described. v

. The shifting, which Arenders it possible that according to the wish of the operator, upon a key being struck, one of two characters widening ofthe projections 22 and is effected in a simple manner owing to the fact that a tooth which is preferably arranged on a rockable double lever 34, upon the shift key being depressed, is brought in front of the stationary projection 22 or 32 and between the latter land the adjustable projections 21 and 31 respectively. The socalled shift key is one of the keys 1 ofthe key-board, and similar to the other vkeys 1 of the key-board. The shift key is connected inV the same manner as the other keys' l to a bar 2. The bar 2, to which the shift key is connected, is provided with a projection 3 l) andiupon the 'shift key being depressed the rod 2 having a'projection 3 is moved in th'edirection of the arrow I) and with its project-ion 3 moves rocking bars el, which b v means of special adjusting hammers 5 of the device 6 travelling through the machine, adjust projections 2l and 31 re# spcctively. than the others and serve merely for the adjusting of the shift levers 34 in that during These projections Vare longer* shifting levers, as shown on' anenlarged scale in Figure lhare brought out of the position in which Ythey lie out of reach of the adjustable projections 2l and 31 into a position in which they place' themselves in front of the projection 22 of the appropriate bar 7 or push bar 10 and come within reach of theadjustable projections.v The releasing of the shift lever is effected owing to the fact that the bent tail-like part of` all the adjusted shift levers 34e runs upfon the above-mentioned cross-.bars 28 or 38 which are carried along in the iiiovement-of the boxes 20 and 30 in the direction of the arrow e, and are held fastuntil the ab-utme-ntsQl, 31 are restored so that the `adjusted levers are rocked back y.into their roriginal positions. The restoring of the adjustable projections 2la and 311*` Y which act upon. the-shift levers, is effected -by a stationary abutment, a stationary bar 3b for example, against which t-he ends of` the said adjusted projections strike at the end of the move-ment of the boxes 2O and 30 in the direction of the arrow e. The holding of the shift levers and of the adjustable projections 2l and 3i inl the position of rest or in theadjusted position may be brought about by any suitable means, as for example by plate-shaped clamping `springs arranged onr the rotating shafts. n
